As shown in FIGS. 32, 33, and 42, the bubble liquid generator X3 is arranged with the other cylindrical end 11B (cylinder lid 12) of the cylindrical body 11 facing the direction of gravity (downward in the vertical direction).

In the bubble liquid generator X3, the liquid W is stored in the storage space C (inside the cylindrical body 11) as described in FIGS. 3 and 13 (see FIGS. 33 and 42).
The bubble liquid generator X3 moves the resistor 3, piston 4, and impeller 65 toward one cylinder end 11A and arranges them at the first position PX in the same manner as described in FIGS. 12 and 13 ( (See FIGS. 42 and 43).

As the resistor 3, piston 4, and impeller 65 move toward one cylindrical end 11A (guide lid 13), the liquid W between the piston 4 and one cylindrical end 11A (guide lid 13) moves as shown in FIG. 41, the liquid flows out through the outer circumference 4a of the piston 4 and the inner circumference 11a of the cylindrical body 11 into the liquid W between the piston 4 and the impeller 65 (vortex space E).

As shown in FIG. 41, the liquid W between the piston 4 and the impeller 65 (vortex space E) moves toward one cylindrical end 11A (guide lid 13) of the resistor 3, the piston 4, and the impeller 65. Accordingly, the impeller 65 is rotated, and the air flows between the resistor 3 and the impeller 65 (injection space D) through each circulation hole 43 and each inflow hole 66 of the impeller disk 42 (impeller 5). The liquid W flows out. The liquid W between the piston 4 and the impeller 65 passes between the outer periphery 42a of the impeller disk 42 and the inner periphery 11a of the cylindrical body 11 (circumferential gap S5), and passes between the resistor 3 and the impeller 65 (injection It flows out into the liquid W in the space D).

In the storage space C, a negative pressure state (negative pressure) occurs between the other cylindrical end 11B and the resistor 3 as the resistor 3 moves toward the one cylindrical end 11A.
As a result, each liquid injection hole 32 (resistor 3) moves as the resistor 3, piston 4, and impeller 65 move toward one cylindrical end 11A (guide lid 13), as shown in FIG. , the liquid W between the resistor 3 and the impeller 65 (injection space D) is injected into the liquid W between the other cylinder end 11B (cylinder lid 12) and the resistor 3.
The liquid W between the resistor 3 and the impeller 65 (injection space D) flows into each liquid injection hole 32 as the resistor 3 moves toward one cylindrical end 11A (guide lid 13). , is injected from each liquid injection hole 32 into the liquid W between the other cylinder end 11B and the resistor 3.
The liquid W between the other cylinder end 11B and the resistor 3 becomes a turbulent flow due to the liquid W in the injection space D injected from each liquid injection hole 32. Cavitation (cave phenomenon) occurs in the liquid W between the other cylinder end 11B and the resistor 3 due to the turbulent pressure difference.
The air (bubbles) in the liquid W at the other tube end 11B and the resistor 3 are pulverized (sheared) into microbubbles and ultrafine bubbles by turbulence and cavitation. The microbubbles and ultrafine bubbles mix and dissolve into the liquid W between the other tube end 11B and the resistor 3.

When the resistor 3, the piston 4, and the impeller 65 are positioned (arranged) at the first position PX, the handle 6 is pushed toward the guide lid 13 (one cylindrical end 11A of the cylindrical body 11), and the piston shaft 2 (large diameter The shaft portion 21) is moved into the cylindrical body 11 (storage space C) (moved in the N direction in FIGS. 33 and 42).
The resistor 3, the piston 4, and the impeller 65 move together with the piston shaft 2 from the first position PX within the cylindrical body 11 (storage space C) toward the other cylindrical end 11B (cylinder lid 12) of the cylindrical body 11. be done.

In the storage space C, a high pressure state (high pressure) is established between the other cylindrical end 11B and the resistor 3 as the resistor 3 moves toward the other cylindrical end 11B.
As a result, each liquid injection hole 32 (resistor 3) is moved toward the other cylindrical end 11B of the piston shaft 2, resistor 3, piston 4, and impeller 65, as shown in FIGS. 44 and 45. Accordingly, the liquid W between the other cylinder end 11B (cylinder lid 12) and the resistor 3 (the liquid W in the storage space C between the other cylinder end 11B and the resistor 3) is transferred to the resistor 3 and the impeller. 65 (injection space D).
Each liquid injection hole 32 injects the liquid W between the resistor 3 (resistance plate surface 3A) and the impeller 65 (disc back surface 42B of the vane disc 42) (injection space D). and generates a flow of liquid W toward the impeller 5 in the liquid W between the impellers 65 and 65 .
As shown in FIGS. 44 and 45, the liquid W between the other cylindrical end 11A and the resistor 3 flows into each liquid injection hole 32 as the resistor 3 moves toward the other cylindrical end 11B. The liquid is then injected from each liquid injection hole 32 between the resistor 3 and the impeller 65 (injection space D).
The liquid W between the resistor 3 and the impeller 65 (injection space D) is moved from the resistor 3 to the impeller in the direction of the axis center line a of the piston shaft 2 by the liquid W injected from each liquid injection hole 32. It flows towards 65.

In the storage space C (inside the cylindrical body 11) between the resistor 3 and the impeller 65, the liquid W flowing from the resistor 3 toward the impeller 65 flows into each circulation hole 43 of the vane disc 42, It collides with (acts on) the back surface 44B of the blade plate 44. The liquid W flowing from the resistor 3 toward the impeller 65 collides with each liquid guide plate 67 of the vane disc 42, flows along each liquid guide plate 67, and flows into each inflow hole 66.
The impeller 65 transfers the kinetic energy of the liquid W flowing in the direction A of the axis center line a of the piston shaft 2 to each blade plate 44 by the collision (action) of the liquid W with each blade plate 44 (the back surface 44B of the blade plate). (Each blade plate 44 tilted at an inclination angle θB) converts it into rotational motion (energy of rotational motion).
The impeller 65 (rotating cylinder part 41 and vane disc 42) rotates clockwise (Q direction in FIGS. 45 and 46) about the piston shaft 2 (large diameter shaft part 21) as the rotation center due to the energy of rotational motion. be done.
Thereby, the impeller 65 is rotated in the Q direction (clockwise) about the shaft center line a of the piston shaft 2 (large diameter shaft portion 21) by the flow of the liquid W toward the impeller 5.
The rotating cylinder portion 41 and the vane disk 42 are rotated in the Q direction (clockwise) with the axial center line a of the piston shaft 2 as the rotation center a.

In the impeller 65, the liquid W that has flowed into each circulation hole 43 and each inflow hole 66 flows between the impeller 65 (disk surface 42A) and the piston 4 (piston back surface 4B), as shown in FIGS. 44 and 45. (vortex space E).

The impeller 65 continuously injects liquid from each liquid injection hole 32 while moving within the cylindrical body 11 (storage space C) toward the other cylinder end 11B together with the piston shaft 2 (resistor 3, piston 4). It is rotated in the Q direction by the liquid W injected into the space D (the flow of the liquid W toward the impeller 65).

The impeller 65 generates a vortex in the liquid W between the piston 4 (piston back surface 4B) and the impeller 65 (disc surface 42A) (vortex space E) by rotation in the Q direction.
The liquid W in the storage space C (vortex space E) between the piston 4 and the impeller 65 becomes a vortex that swirls in the Q direction about the axial center line a of the piston shaft 2 due to the rotation of the impeller 65. The vortex is swirled around the piston shaft 2 (large diameter shaft portion 21) in the vortex space E.
The liquid W (part of the liquid W) between the piston 4 and the impeller 65 (vortex space E) moves toward the other cylindrical end 11B of the piston shaft 2 (resistor 3, piston 4, and impeller 65). Accordingly, it flows out from between the outer periphery 4a of the piston 4 and the inner periphery 11a of the cylindrical body 11 (circumferential gap S4) to one cylindrical end 11A side.

The liquid W between the piston 4 and the impeller 65 becomes a turbulent flow due to the vortex in the vortex space E. Cavitation (cave phenomenon) occurs in the liquid W between the piston 4 and the impeller 65 (vortex space E) due to the pressure difference of the vortex.
Air (bubbles) in the liquid W between the piston 4 and the impeller 65 (vortex space E) is crushed (sheared) into microbubbles and ultrafan bubbles by the vortex (turbulent flow) and cavitation. The microbubbles and ultrafine bubbles mix and dissolve into the liquid W between the piston 4 and the impeller 5 (vortex space E).
In this way, the bubble liquid generator X3 rotates the impeller 65 to generate a vortex in the liquid W between the piston 4 and the impeller 65 (the vortex space E). of air (gas) can be pulverized (sheared) into fine bubbles, and a large amount of microbubbles and a large amount of ultrafine bubbles can be mixed and dissolved into the liquid W.

In the bubble liquid generator X3, by pulling up the handle 6 from the guide lid 13 and pushing it toward the guide lid 13, the piston shaft 2, the resistor 3, the piston 4, and the impeller 65 are moved to each end of the cylindrical body 11. It reciprocates between 11A and 11B (between cylinder lid 12 and guide lid 13).
The bubble liquid generator X3 can generate turbulence in the liquid W between the other cylinder end 11B and the resistor 3 multiple times by reciprocating the resistor 3, piston 4, and impeller 65 multiple times. , a vortex can be generated multiple times in the liquid W between the piston 4 and the impeller 65 (vortex space E), and a sufficient amount (a large amount) of microbubbles and a sufficient amount (a large amount) of ultrafine are generated by the multiple vortices. It becomes possible to mix and dissolve bubbles into the liquid W.

As shown at 54, the liquid flows through the outer circumference 4a of the piston 4 and the inner circumference 11a of the cylindrical body 11, and flows out into the liquid W between the piston 4 and the impeller 75 (vortex space E).

The liquid W between the piston 4 and the impeller 75 (vortex space E) moves toward one cylindrical end 11A (guide lid 13) of the resistor 3, the piston 4, and the impeller 75, as shown in FIG. As a result, the impeller 75 is rotated, and the liquid W flows through each inclined flow path τ to the liquid W between the resistor 3 and the impeller 75 (injection space D). The liquid W between the piston 4 and the impeller 75 passes between the outer periphery 42a of the impeller disk 42 and the inner periphery 11a of the cylindrical body 11 (peripheral gap S5), and passes between the resistor 3 and the impeller 75 (injection It flows out into the liquid W in the space D).

In the storage space C, a negative pressure state (negative pressure) is created between the other cylindrical end 11B and the resistor 3 as the resistor 3 moves toward the one cylindrical end 11A.
As a result, each liquid injection hole 32 (resistor 3) moves as the resistor 3, piston 4, and impeller 75 move toward one cylindrical end 11A (guide lid 13), as shown in FIG. , the liquid W between the resistor 3 and the impeller 75 (injection space D) is injected into the liquid W between the other cylinder end 11B (cylinder lid 12) and the resistor 3.
The liquid W between the resistor 3 and the impeller 75 (injection space D) flows into each liquid injection hole 32 as the resistor 3 moves toward one cylindrical end 11A (guide lid 13). , is injected from each liquid injection hole 32 into the liquid W between the other cylinder end 11B and the resistor 3.
The liquid W between the other cylinder end 11B and the resistor 3 becomes a turbulent flow due to the liquid W in the injection space D injected from each liquid injection hole 32. Cavitation (cave phenomenon) occurs in the liquid W between the other cylinder end 11B and the resistor 3 due to the turbulent pressure difference.
The air (bubbles) in the liquid W at the other tube end 11B and the resistor 3 are pulverized (sheared) into microbubbles and ultrafine bubbles by turbulence and cavitation. The microbubbles and ultrafine bubbles mix and dissolve into the liquid W between the other tube end 11B and the resistor 3.

When the resistor 3, the piston 4, and the impeller 75 are positioned (arranged) at the first position PX, the handle 6 is pushed toward the guide lid 13 (one cylindrical end 11A of the cylindrical body 11), and the piston shaft 2 (large diameter The shaft portion 21) is moved into the cylindrical body 11 (storage space C) (moved in the N direction in FIGS. 48 and 55).
The resistor 3, the piston 4, and the impeller 75 move together with the piston shaft 2 from the first position PX within the cylindrical body 11 (storage space C) toward the other cylindrical end 11B (cylinder lid 12) of the cylindrical body 11. be done.

In the storage space C, a high pressure state (high pressure) occurs between the other cylindrical end 11B and the resistor 3 as the resistor 3 moves toward the other cylindrical end 11B.
As a result, each liquid injection hole 32 (resistor 3) moves toward the other cylinder end 11B of the piston shaft 2, the resistor 3, the piston 4, and the impeller 75, and The liquid W between the lid 12) and the resistor 3 (the liquid W in the storage space C between the other cylinder end 11B and the resistor 3) is injected into between the resistor 3 and the impeller 75 (injection space D). do.
As a result, each liquid injection hole 32 injects the liquid W between the resistor 3 (resistance plate surface 3A) and the impeller 75 (disk back surface 42B of the vane disk 42) (injection space D). A flow of liquid W toward the impeller 5 is generated between the resistor 3 and the impeller 75 .
The liquid W between the other cylindrical end 11A and the resistor 3 flows into each liquid injection hole 32 as the resistor 3 moves toward the other cylindrical end 11B. It is injected between the body 3 and the impeller 75 (injection space D).
As shown in FIGS. 57 and 58, the liquid W between the resistor 3 and the impeller 75 (injection space D) is moved along the axial center line a of the piston shaft 2 by the liquid W injected from each liquid injection hole 32. Flows from the resistor 3 toward the impeller 75 in the direction of .

In the storage space C (inside the cylindrical body 11) between the resistor 3 and the impeller 75, the liquid W flowing from the resistor 3 toward the impeller 75 flows through each inclined flow path τ of the impeller 75 (each vane plate 77). (between) and collides with (acts on) the back surface 77A of each vane plate 77.
The impeller 75 transfers the kinetic energy of the liquid W flowing at an inclination angle θD to each vane plate 77 (each inclined at an inclination angle θD) by the collision (action) of the liquid W on each vane plate 77 (curved plate surface 77A). It is converted into rotational motion (energy of rotational motion) by the vane plate 77).
The impeller 75 (rotating cylinder part 41) is rotated counterclockwise (direction V in FIGS. 58 and 59) about the piston shaft 2 (large diameter shaft part 21) as a rotation center by the energy of the rotational motion.
As a result, the impeller 75 is rotated in the V direction (counterclockwise) about the axis center line a of the piston shaft 2 (large diameter shaft portion 21) by the flow of the liquid W toward the impeller 75. .

In the impeller 75, the liquid W flowing into each inclined flow path τ flows between the impeller 75 (the other rotary tube end 41B) and the piston 4 (the back surface 4B of the piston) (vortex flow), as shown in FIGS. 57 and 58. It flows out into space E).

The impeller 75 continuously injects liquid from each liquid injection hole 32 while moving within the cylindrical body 11 (storage space C) toward the other cylinder end 11B together with the piston shaft 2 (resistor 3, piston 4). It is rotated in the V direction by the liquid W injected into the space D (the flow of the liquid W toward the impeller 75).

By rotating in the V direction, the impeller 75 generates a vortex in the liquid W between the piston 4 (piston back surface 4B) and the impeller 75 (the other rotating tube end 41B) (in the vortex space E).
The liquid W in the storage space C (vortex space E) between the piston 4 and the impeller 75 becomes a vortex that swirls in the V direction about the axial center line a of the piston shaft 2 due to the rotation of the impeller 75. The vortex is swirled around the piston shaft 2 (large diameter shaft portion 21) in the vortex space E.
The liquid W (part of the liquid W) between the piston 4 and the impeller 75 (vortex space E) moves toward the other cylindrical end 11B of the piston shaft 2 (resistor 3, piston 4, and impeller 75). Accordingly, it flows out from between the outer periphery 4a of the piston 4 and the inner periphery 11a of the cylindrical body 11 (circumferential gap S4) to one cylindrical end 11A side.

The liquid W between the piston 4 and the impeller 75 becomes turbulent in the vortex space E due to the vortex. Cavitation (cave phenomenon) occurs in the liquid W between the piston 4 and the impeller 75 (vortex space E) due to the pressure difference of the vortex.
Air (bubbles) in the liquid W between the piston 4 and the impeller 75 (vortex space E) is crushed (sheared) into microbubbles and ultrafan bubbles by the vortex (turbulent flow) and cavitation. The microbubbles and ultra-fine bubbles mix and dissolve into the liquid W between the piston 4 and the impeller 75 (vortex space E).
In this way, the bubble liquid generator X4 rotates the impeller 75 to generate a vortex in the liquid W between the piston 4 and the impeller 75 (the vortex space E). of air (gas) can be pulverized (sheared) into fine bubbles, and a large amount of microbubbles and a large amount of ultrafine bubbles can be mixed and dissolved into the liquid W.

In the bubble liquid generator It reciprocates between 11A and 11B (between cylinder lid 12 and guide lid 13).
The bubble liquid generator X4 can generate turbulence in the liquid W between the other cylinder end 11B and the resistor 3 multiple times by reciprocating the resistor 3, piston 4, and impeller 75 multiple times. , a vortex can be generated multiple times in the liquid W between the piston 4 and the impeller 75 (vortex space E), and a sufficient amount (a large amount) of microbubbles and a sufficient amount (a large amount) of ultrafine are generated by the multiple vortices. It becomes possible to mix and dissolve bubbles into the liquid W.

As the resistor 3, piston 4, and impeller 85 move toward one cylindrical end 11A (guide lid 13), the liquid W between the piston 4 and one cylindrical end 11A (guide lid 13) moves as shown in FIG. As shown in 67, the liquid passes through the outer circumference 4a of the piston 4 and the inner circumference 11a of the cylindrical body 11, and flows out into the liquid W between the piston 4 and the impeller 85 (vortex space E).

As shown in FIG. 67, the liquid W between the piston 4 and the impeller 85 (vortex space E) moves toward one cylindrical end 11A (guide lid 13) of the resistor 3, the piston 4, and the impeller 85. Accordingly, the impeller 85 is rotated, and the liquid W flows through each inclined flow path λ to the liquid W between the resistor 3 and the impeller 85 (injection space D).

The liquid W between the other cylinder end 11B and the resistor 3 becomes a turbulent flow due to the liquid W in the injection space D injected from each liquid injection hole 32. Cavitation (cave phenomenon) occurs in the liquid W between the other cylinder end 11B and the resistor 3 due to the turbulent pressure difference.
The air (bubbles) in the liquid W at the other tube end 11B and the resistor 3 are pulverized (sheared) into microbubbles and ultrafine bubbles by turbulence and cavitation. The microbubbles and ultrafine bubbles mix and dissolve into the liquid W between the other tube end 11B and the resistor 3.

When the resistor 3, the piston 4, and the impeller 85 are positioned (arranged) at the first position PX, the handle 6 is pushed toward the guide lid 13 (one cylindrical end 11A of the cylindrical body 11), and the piston shaft 2 (large diameter The shaft portion 21) is moved into the cylindrical body 11 (storage space C) (moved in the N direction in FIGS. 61 and 68).
The resistor 3, the piston 4, and the impeller 85 move together with the piston shaft 2 from the first position PX within the cylindrical body 11 (storage space C) toward the other cylindrical end 11B (cylinder lid 12) of the cylindrical body 11. be done.

In the storage space C, a high pressure state (high pressure) is established between the other cylindrical end 11B and the resistor 3 as the resistor 3 moves toward the other cylindrical end 11B.

Each liquid injection hole 32 injects the liquid W between the resistor 3 (resistance plate surface 3A) and the impeller 85 (one rotating cylinder end 41A of the rotating cylinder part 41) (injection space D). A flow of liquid W toward the impeller 85 is generated between the body 3 and the impeller 85.
The liquid W between the other cylindrical end 11A and the resistor 3 (the liquid W in the storage space C between the other cylindrical end 11A and the resistor 3) is as shown in FIGS. As the liquid moves toward the other cylindrical end 11B, it flows into each liquid injection hole 32 and is injected from each liquid injection hole 32 between the resistor 3 and the impeller 85 (injection space D).
The liquid W between the resistor 3 and the impeller 85 (injection space D) is moved from the resistor 3 to the impeller in the direction of the axis center line a of the piston shaft 2 by the liquid W injected from each liquid injection hole 32. It flows towards 85.

In the storage space C (inside the cylindrical body 11) between the resistor 3 and the impeller 85, the liquid W flowing from the resistor 3 toward the impeller 85 flows through each inclined flow path λ of the impeller 85 (each vane plate 87). (between) and collides with (acts on) the curved plate surface 87A of each vane plate 87.
The impeller 85 transfers the kinetic energy of the liquid W flowing at an inclination angle θE to each vane plate 87 (each inclined at an inclination angle θE) by the collision (action) of the liquid W with each vane plate 87 (curved plate surface 87A). It is converted into rotational motion (energy of rotational motion) by the vane plate 87).
The impeller 85 (rotating cylinder part 41) is rotated counterclockwise (direction V in FIGS. 71 and 72) about the piston shaft 2 (large diameter shaft part 21) as a rotation center by the energy of the rotational motion.
As a result, the impeller 85 is rotated in the V direction (counterclockwise) about the axis center line a of the piston shaft 2 (large diameter shaft portion 21) by the flow of the liquid W toward which the impeller 85 is directed. .

In the impeller 85, the liquid W flowing into each inclined flow path τ flows between the impeller 85 (the other rotary cylinder end 41B) and the piston 4 (the back surface 4B of the piston) (vortex flow), as shown in FIGS. 70 and 71. It flows out into space E).

The impeller 85 continuously injects liquid from each liquid injection hole 32 while moving within the cylindrical body 11 (storage space C) toward the other cylinder end 11B together with the piston shaft 2 (resistor 3, piston 4). It is rotated in the V direction by the liquid W injected into the space D (the flow of the liquid W toward the impeller 85).

By rotating in the V direction, the impeller 85 generates a vortex in the liquid W between the piston 4 (piston back surface 4B) and the impeller 85 (the other rotary tube end 41B) (in the vortex space E).
The liquid W in the storage space C (vortex space E) between the piston 4 and the impeller 85 becomes a vortex that swirls in the V direction about the axial center line a of the piston shaft 2 due to the rotation of the impeller 85. The vortex is swirled around the piston shaft 2 (large diameter shaft portion 21) in the vortex space E.
The liquid W (part of the liquid W) between the piston 4 and the impeller 85 (vortex space E) moves toward the other cylindrical end 11B of the piston shaft 2 (resistor 3, piston 4, and impeller 85). Accordingly, it flows out from between the outer periphery 4a of the piston 4 and the inner periphery 11a of the cylindrical body 11 (circumferential gap S4) to one cylindrical end 11A side.

The liquid W between the piston 4 and the impeller 85 becomes turbulent in the vortex space E due to the vortex. Cavitation (cave phenomenon) occurs in the liquid W between the piston 4 and the impeller 85 (vortex space E) due to the pressure difference of the vortex.
Air (bubbles) in the liquid W between the piston 4 and the impeller 85 (vortex space E) is crushed (sheared) into microbubbles and ultrafan bubbles by the vortex (turbulence) and cavitation. The microbubbles and ultra-fine bubbles mix and dissolve into the liquid W between the piston 4 and the impeller 85 (vortex space E).

It becomes possible to mix and dissolve bubbles into the liquid W.
